Fluorite, also named fluorspar, is mainly composed of calcium fluoride and has a wide range of uses, such as in the steel industry as a flux, in enamel color and flux, in the optical field for lenses, acid-grade fluorite powder can be used for production Hydrofluoric  acid.  Fluorite is the main source of almost all fluorine.

   As the world's largest fluorite producer and consumer, China has the world's largest fluorite ore reserves and relatively concentrated fluorite ore reserves, of which Zhejiang province, Hunan province and Inner Mongolia province account for about 72% of the domestic reserves, and these reserves are relatively concentrated. For several large deposits, the characteristics of domestic fluorite mines are more single-type fluorite deposits, less reserves, more lean ore, less rich ore, and more fluorite associated ore, large reserves, more difficult beneficiation. As a result, the utilization value of fluorite ore is greatly limited.

   At this stage, the main beneficiation methods of domestic fluorite ore are as follows, hand selection, gravity (jig) selection and flotation . Among them, hand selection is mainly based on the clear boundary between fluorite and gangue, which is suitable for easy separation of fluorite. Gravity selection mainly selects fluorite ore with higher grade and particle size of 6-20mm, and flotation is mainly used to separate fluorite from Quartz, barite, calcite and other gangue minerals . They need to be ground below -200 mesh for sorting.

All above types of separation have great limitations, low efficiency of manual selection, high personnel cost; high grade requirements for gravity separation, high requirements for optional fluorite ore; high cost of flotation and great damage to the environment. There is an urgent need for improvement in terms of technology, cost, resource utilization, and economic benefits.

  Then a new ore sorting equipment mentioned today - Artificial Intelligence ore sorting machine, which is perfectly compatible with the process content of hand selection + gravity selection, and at the same time reduces the amount of flotation ore through sorting, and solves the problem. The problem of low accuracy of fluorite sorting by color sorter.

   The main application field of Artificial Intelligence ore sorting machine is industrial and mining enterprises, mainly using visible light for sorting, using mature Artificial Intelligence methods, and can sort according to the various differences of ore seen by the eyes, such as color, shape, texture , reflectivity and other characteristics, the sorting is a composite one-time sorting, combined with a model established by various characteristics, the control system identifies the good material and the tail material, which solves the problem that the color sorter can only judge based on a single color limited. Especially in fluorite ore, because of its different colors and crystal shapes, such as octahedral, cubic, granular, grape-like, spherical, etc., the characteristics are very different, and the sorting is difficult. The application of artificial intelligence machine is very promising.

   First of all, compared with manual ore sorting, the artificial intelligence ore sorting machine has the advantages of strong stability and large sorting magnitude; compared with gravity sorting, high-grade fluorite and low-grade fluorite with a particle size of 0.3-10cm can be sorted. It breaks the limitation of gravity separation; compared with flotation, after crushing and dissociation, fluorite can directly enter the artificial intelligence ore sorting machine to pre-dump fluorite ore, and sort out fluorite concentrate and waste raw ore. Among them, the fluorite concentrate can be sold directly, and the waste rock can be backfilled or sold as building materials; for the fluorite ore that is not easy to dissociate, we can sort out the high-grade fluorite for enrichment. The direct waste disposal of the grade reduces the amount of ore for flotation and saves the cost of flotation, and at the same time reduces the processing volume and processing cost of tailings after flotation.

   Facing industrial and mining enterprises, Mingde Artificial Intelligence Ore Sorting Machine  can adapt to the requirements of harsh environments such as high dust, high pollution and high corrosion. At the same time, it improves the comprehensive utilization and economic value of fluorite ore, and reduces the mining grade requirements. Mingde Artificial Intelligence Ore Sorting Machine  has been helping to solve the sorting problems of industrial and mining enterprises.
